Using a nonlinear electrodynamics coupled to General Relativity a new regular exact black
hole solution is found. The nonlinear theory reduces to the Maxwell one in the weak limit …

It is a pleasure for me to contribute to the Yuri Golfand memorial volume. I met Yuri several
times during his occasional visits of Lebedev Institute in the 80's. Two of our discussions in …

Motivated by the possible experimental opportunities to test quantum gravity via its effects on
high-energy neutrinos propagating through space-time foam, we discuss how to incorporate …

Locally concentrated solutions in the Born–Infeld theory are presented. In particular,
existence and uniqueness theorems are established for multicentred magnetic string …

We study maps from a 2‐surface into the standard 2‐sphere coupled with Born‐Infeld
geometric electromagnetism through an Abelian gauge field. Such a formalism extends the …

Abstract The Dirac-Born-Infeld action with transverse scalar fields is considered to study the
dynamics of various Bogomol'nyi-Prasad-Sommerfield (BPS) states. We first describe the …

Using the natural curvature invariants as building blocks in a superfield construction, we
show that the use of a symmetric trace is mandatory if one is to reproduce the square root …

Abstract Motivated by Born–Infeld geometric electromagnetic theory, we consider a series of
nonlinear equations which extend the minimal surface equations and the related …

Standard methods of nonlinear dynamics are used to investigate the stability of particles,
branes and D-branes of abelian Born–Infeld theory. In particular the equation of small …

I discuss in these lectures vortex-like classical solutions to the equations of motion of gauge
theories with spontaneous symmetry breaking. Starting from the Nielsen-Olesen ansatz for …
